The first sentence of HELP -> SHIFT is: "Purpose: Allows the use of more than 512 parameters in a batch file, or iterating through its parameters. This command can be used only in batch files." In V05 the number was 256, since V06 the number is 512. In V08 and earlier versions the number matched the number of parameters directly accessible as %n. However, since V09 one can access up to 4096 parameters as %n. Shouldn't the number be updated?
